Edit : Went for a walk to cool off, and still it would be absolutely and utterly overpowered beyond any repair, forever. Close your eyes and listen.. Can you hear it? The cries for nerf? The card isn't even real, and there are ALREADY 5 threads to make it a Warsong Commander.

Edit 2 : It's so ****** broken that it would make Blade Flurry usable.

I don't see it. What's so special about a 5/1 weapon? For single target removal, there's Envenom Weapon and for aoe it seems too conditional. You'd need 7 Mana, 2 (otherwise dead) cards and a weapon equipped.

I feel like this card would be better in aggressive Handbuffpaladin. It would do 12 damage with one buff, 21 with two and 60 with Han'Cho.

I like the Arcane Dance spell. Can give some combo possibilities by using Pyroblast & 0 or 1 cost spell. But you can also draw two pyroblasts or two one cost spells or your second copy... Also a bit pricy at 5 mana, 4 mana would make more sense.
